That is, as shown in FIG. 4, the first and second guide members 18 and 19 are provided facing the front and rear directions with the first and second connecting members 16 and 17 and the cylinder device 22 interposed therebetween. Yes. In this case, the first and second guide members 18 and 19 intersect the cylinder device 22 on both sides in the front-rear direction of the cylinder device 22.
そして、第1ガイド部材18の一端と第2ガイド部材19の一端は、第1連結部材16の第2の頂部16Bに対して、ピン結合によりピン16B1を回転中心とした左,右方向の揺動を可能に接続されている。また、第1ガイド部材18の他端と第2ガイド部材19の他端は、第2連結部材17の第2の頂部17Bに対して、ピン結合によりピン17B1を回転中心とした左,右方向の揺動を可能に接続されている。
Then, one end of the first guide member 18 and one end of the second guide member 19 are rocked in the left and right directions around the pin 16B1 as a rotation center by pin connection with respect to the second top portion 16B of the first connecting member 16. Connected to allow movement. Further, the other end of the first guide member 18 and the other end of the second guide member 19 are connected to the second top portion 17B of the second connecting member 17 in the left and right directions with the pin 17B1 as the rotation center by pin connection. It is connected so that it can swing.
上部摩擦材20は、第1連結部材16の一側側面と第1ガイド部材18との間および第1連結部材16の他側側面と第2ガイド部材19との間に、それぞれ設けられている。上部摩擦材20は、例えば樹脂材やゴム材や鉄材等を用いて筒状に形成され、ピン16B1を介して、第1連結部材16と第1ガイド部材18との間および第1連結部材16と第2ガイド部材19との間に接続されている(図4,図5参照)。この上部摩擦材20は、構造物の振動時に、第1連結部材16と第1ガイド部材18との間および第1連結部材16と第2ガイド部材19との間に摩擦抵抗を生じさせるものである。
The upper friction material 20 is provided between one side surface of the first connecting member 16 and the first guide member 18 and between the other side surface of the first connecting member 16 and the second guide member 19. . The upper friction material 20 is formed in a cylindrical shape using, for example, a resin material, a rubber material, an iron material, or the like, and is interposed between the first connection member 16 and the first guide member 18 and the first connection member 16 via the pin 16B1. And the second guide member 19 (see FIGS. 4 and 5). The upper friction member 20 generates frictional resistance between the first connecting member 16 and the first guide member 18 and between the first connecting member 16 and the second guide member 19 when the structure vibrates. is there.
即ち、上部摩擦材20は、第1ガイド部材18および第2ガイド部材19が第1連結部材16に対してピン16B1を中心に揺動しようとすることに対する抵抗となるものである。これにより、第1連結部材16の第2の頂部16Bと第1ガイド部材18および第2ガイド部材19との間に、上部摩擦材20による摩擦抵抗より大きい力が加わった場合に、第2の頂部16Bがピン16B1を中心に揺動し始める。言い換えれば、上部摩擦材20は、第2の頂部16Bの揺動が始まるまで、筋交いとして構造物の強度を確保する(振動を抑える)ものである。
That is, the upper friction material 20 provides resistance to the first guide member 18 and the second guide member 19 from swinging around the pin 16B1 with respect to the first connecting member 16. Thus, when a force greater than the frictional resistance of the upper friction material 20 is applied between the second top portion 16B of the first connecting member 16 and the first guide member 18 and the second guide member 19, the second The top portion 16B starts to swing around the pin 16B1. In other words, the upper friction material 20 secures the strength of the structure as a brace (suppresses vibration) until the second top portion 16B starts to swing.
下部摩擦材21は、第2連結部材17の一側側面と第1ガイド部材18との間および第2連結部材17の他側側面と第2ガイド部材19との間に、それぞれ設けられている。下部摩擦材21は、例えば樹脂材やゴム材や鉄材等を用いて筒状に形成され、ピン17B1を介して、第2連結部材17と第1ガイド部材18との間および第2連結部材17と第2ガイド部材19との間に接続されている(図4参照)。この下部摩擦材21は、構造物の振動時に、第2連結部材17と第1ガイド部材18との間および第2連結部材17と第2ガイド部材19との間に摩擦抵抗を生じさせるものである。
The lower friction material 21 is provided between one side surface of the second connecting member 17 and the first guide member 18 and between the other side surface of the second connecting member 17 and the second guide member 19. . The lower friction member 21 is formed in a cylindrical shape using, for example, a resin material, a rubber material, an iron material, or the like, and is interposed between the second connecting member 17 and the first guide member 18 and the second connecting member 17 via the pin 17B1. And the second guide member 19 (see FIG. 4). The lower friction member 21 generates frictional resistance between the second connecting member 17 and the first guide member 18 and between the second connecting member 17 and the second guide member 19 when the structure vibrates. is there.
即ち、下部摩擦材21は、第1ガイド部材18および第2ガイド部材19が第2連結部材17に対してピン17B1を中心に揺動しようとすることに対する抵抗となるものである。これにより、第2連結部材17の第2の頂部17Bと第1ガイド部材18および第2ガイド部材19との間に、下部摩擦材21による摩擦抵抗より大きい力が加わった場合に、第2の頂部17Bがピン17B1を中心に揺動し始める。言い換えれば、下部摩擦材21は、第2の頂部17Bの揺動が始まるまで、筋交いとして構造物の強度を確保する(振動を抑える)ものである。
That is, the lower friction material 21 serves as a resistance against the first guide member 18 and the second guide member 19 trying to swing around the pin 17B1 with respect to the second connecting member 17. Thus, when a force greater than the frictional resistance of the lower friction material 21 is applied between the second top portion 17B of the second connecting member 17 and the first guide member 18 and the second guide member 19, the second The top portion 17B starts to swing around the pin 17B1. In other words, the lower friction material 21 secures the strength of the structure as a brace (suppresses vibration) until the second top portion 17B starts to swing.
シリンダ装置22は、第1連結部材16と第2連結部材17との上,下方向の間に位置すると共に、第1ガイド部材18と第2ガイド部材19との前,後方向の間に設けられている。このシリンダ装置22は、例えばフリーピストンタイプのシリンダ装置により構成され、作動油が充填されたシリンダ22Aと、シリンダ22A内を摺動するピストン(図示せず)と、該ピストンに結合されたピストンロッド22Bを有している。このシリンダ装置22は、第1連結部材16、第2連結部材17、第1ガイド部材18、第2ガイド部材19と共に、リンク機構を構成している。
The cylinder device 22 is positioned between the first connecting member 16 and the second connecting member 17 in the upper and lower directions, and is provided between the first guide member 18 and the second guide member 19 in the front and rear directions. It has been. The cylinder device 22 is constituted by, for example, a free piston type cylinder device, and includes a cylinder 22A filled with hydraulic oil, a piston (not shown) that slides in the cylinder 22A, and a piston rod coupled to the piston. 22B. The cylinder device 22 constitutes a link mechanism together with the first connecting member 16, the second connecting member 17, the first guide member 18, and the second guide member 19.
ピストンロッド22Bの端部は、第1連結部材16の第3の頂部16Cとピン16C1を介して左,右方向に揺動可能に接続されている。また、シリンダ22Aの端部は、第2連結部材17の第3の頂部17Cと第2取付部としてのピン17C1を介して左,右方向に揺動可能に接続されている。即ち、シリンダ装置22の一側(ピストンロッド22B側)は、第1連結部材16を介して第1連結部材16のピン16C1に第1棒状体12の他端と接続され、シリンダ装置22の他側(シリンダ22A側)は、第2連結部材17を介して第2連結部材17のピン17C1に第2棒状体14の一端と接続されている。これにより、シリンダ装置22は、構造物の振動による相対変位を、ピストンロッド22Bが伸長、縮小することによって(ピストンに設けた小孔(図示せず)を油が流通することによって)減衰させる。
The end of the piston rod 22B is connected to the third top portion 16C of the first connecting member 16 and a pin 16C1 so as to be swingable in the left and right directions. Further, the end portion of the cylinder 22A is connected to be swingable in the left and right directions via the third top portion 17C of the second connecting member 17 and the pin 17C1 as the second attachment portion. That is, one side (piston rod 22B side) of the cylinder device 22 is connected to the pin 16C1 of the first connecting member 16 via the first connecting member 16 and the other end of the first rod-shaped body 12, and the other side of the cylinder device 22 is connected. The side (cylinder 22 </ b> A side) is connected to the pin 17 </ b> C <b> 1 of the second connecting member 17 with one end of the second rod-like body 14 through the second connecting member 17. Thereby, the cylinder device 22 attenuates the relative displacement due to the vibration of the structure (the oil flows through a small hole (not shown) provided in the piston) by the piston rod 22B extending and contracting.
この場合、シリンダ装置22は、第1連結部材16の第3の頂部16Cと第2連結部材17の第3の頂部17Cとの間で、左側から右側に向けて斜め上向きに延びている。一方、第1,第2ガイド部材18,19は、第1連結部材16の第2の頂部16Bと第2連結部材17の第2の頂部17Bとの間で、右側から左側に向けて斜め上向きに延びている。これにより、シリンダ装置22と第1,第2ガイド部材18,19とは、左,右方向にクロス(立体交差)して、図1に示す正面視でX字状をなしている。
In this case, the cylinder device 22 extends obliquely upward from the left side to the right side between the third top portion 16C of the first connecting member 16 and the third top portion 17C of the second connecting member 17. On the other hand, the first and second guide members 18 and 19 are diagonally upward from the right side to the left side between the second top portion 16B of the first connecting member 16 and the second top portion 17B of the second connecting member 17. It extends to. Thereby, the cylinder device 22 and the first and second guide members 18 and 19 cross in the left and right directions (three-dimensional intersection), and form an X shape in a front view shown in FIG.
ここで、リンク機構は、第1連結部材16、第2連結部材17、第1ガイド部材18、第2ガイド部材19、シリンダ装置22により構成されている。このリンク機構は、第1棒状体12と第2棒状体14との間を接続している。リンク機構は、構造物の振動時に、上梁1Aと下梁1Bとの間の左,右方向の相対変位を、シリンダ装置22に対して該シリンダ装置22の軸方向の変位(ないし、これに近い方向の変位)に変換して伝達するものである。
Here, the link mechanism includes a first connecting member 16, a second connecting member 17, a first guide member 18, a second guide member 19, and a cylinder device 22. This link mechanism connects the first rod-shaped body 12 and the second rod-shaped body 14. When the structure is vibrated, the link mechanism moves the relative displacement in the left and right directions between the upper beam 1A and the lower beam 1B with respect to the cylinder device 22 in the axial direction of the cylinder device 22 (or to this). (Displacement in the near direction).
本実施の形態による制振装置11は、上述の如き構成を有するもので、次に、その作動について図6および図7を用いて説明する。なお、図6および図7では、構造物に振動が加わっていない中立状態を二点鎖線で示している。
The vibration damping device 11 according to the present embodiment has the above-described configuration. Next, the operation thereof will be described with reference to FIGS. 6 and 7. In FIGS. 6 and 7, a neutral state in which no vibration is applied to the structure is indicated by a two-dot chain line.
制振装置11が取付けられた構造物に、例えば地震等により水平方向の振動が入力されると、上梁1Aおよび下梁1Bを介して左柱2Aと右柱2Bとの間で水平方向の相対変位が生じる。左柱2Aと右柱2Bとの間で生じた相対変位は、上部固定部材13、下部固定部材15、第1棒状体12、第2棒状体14、第1連結部材16、第2連結部材17を通じて、シリンダ装置22に入力される。
When horizontal vibration is input to the structure to which the vibration control device 11 is attached, for example, due to an earthquake or the like, the horizontal vibration is generated between the left column 2A and the right column 2B via the upper beam 1A and the lower beam 1B. Relative displacement occurs. The relative displacement generated between the left column 2A and the right column 2B is the upper fixing member 13, the lower fixing member 15, the first rod-like body 12, the second rod-like member 14, the first connecting member 16, and the second connecting member 17. Through the cylinder device 22.
このとき、図6に示すように、上梁1Aが下梁1Bに対して、二点鎖線で示す中立位置から実線で示す左側位置に変位(相対変位)した場合は、上梁1Aと共に左柱2Aの上端および右柱2Bの上端が中立位置に対して左方向に変位することにより、第1棒状体12も左方向に向けて変位する。このとき、第1棒状体12は、上梁1Aに対して揺動不能に固定されているため、第1棒状体12は、例えば、上梁1Aとのなす角度が中立位置のときのなす角度のまま、左方向に変位する。これに伴って、第1連結部材16が左方向に変位するが、このとき、第1連結部材16は、第1,第2ガイド部材18,19によって第2連結部材17との距離(ピン16B1とピン17B1との距離)が一定に維持されるため、第1連結部材16は、左方向に変位しつつ反時計回り方向に揺動する。また、第1,第2ガイド部材18,19と接続されている第2連結部材17は、第1連結部材16が左方向に変位することに伴って、第1の頂部17Aのピン17A1を中心として反時計回り方向に揺動する。
At this time, as shown in FIG. 6, when the upper beam 1A is displaced (relatively displaced) from the neutral position indicated by the two-dot chain line to the left position indicated by the solid line with respect to the lower beam 1B, the left column is combined with the upper beam 1A. When the upper end of 2A and the upper end of the right column 2B are displaced leftward with respect to the neutral position, the first rod-like body 12 is also displaced leftward. At this time, since the first rod-like body 12 is fixed so as not to swing with respect to the upper beam 1A, the first rod-like body 12 is, for example, an angle formed when the angle formed with the upper beam 1A is the neutral position. Displace to the left. Along with this, the first connecting member 16 is displaced leftward. At this time, the first connecting member 16 is separated from the second connecting member 17 by the first and second guide members 18 and 19 (pin 16B1). Since the distance between the pin 17B1 and the pin 17B1 is maintained constant, the first connecting member 16 swings counterclockwise while being displaced leftward. The second connecting member 17 connected to the first and second guide members 18 and 19 is centered on the pin 17A1 of the first apex portion 17A as the first connecting member 16 is displaced leftward. Swings counterclockwise.
これにより、ピストンロッド22Bが接続されている第1連結部材16の第3の頂部16Cとシリンダ22Aが接続されている第2連結部材17の第3の頂部17Cとは、シリンダ装置22の軸方向の互いに離れる方向に変位する。このため、シリンダ装置22のピストンロッド22Bが中立状態の縮小位置から伸長方向に変位する。そして、シリンダ装置22は、シリンダ22A内をピストンが変位することにより減衰力を発生して、構造物の振動エネルギを吸収する。
Thus, the third top portion 16C of the first connecting member 16 to which the piston rod 22B is connected and the third top portion 17C of the second connecting member 17 to which the cylinder 22A is connected are in the axial direction of the cylinder device 22. Displacement in the direction away from each other. For this reason, the piston rod 22B of the cylinder device 22 is displaced in the extending direction from the reduced position in the neutral state. The cylinder device 22 absorbs vibration energy of the structure by generating a damping force when the piston is displaced in the cylinder 22A.
一方、上梁1Aが下梁1Bに対して、実線で示す左側位置から二点鎖線で示す中立位置に戻るときは、第1連結部材16が右方向に変位しつつ時計回り方向に揺動すると共に、第2連結部材17が時計回り方向に揺動する。このとき、第1連結部材16の第3の頂部16Cと第2連結部材17の第3の頂部17Cとは、シリンダ装置22の軸方向の互いに近付く方向に変位する。これにより、シリンダ装置22のピストンロッド22Bが、伸長位置から中立状態の縮小位置に戻りつつ、減衰力を発生する。
On the other hand, when the upper beam 1A returns from the left position indicated by the solid line to the neutral position indicated by the two-dot chain line with respect to the lower beam 1B, the first connecting member 16 swings clockwise while being displaced rightward. At the same time, the second connecting member 17 swings in the clockwise direction. At this time, the third top portion 16 </ b> C of the first connecting member 16 and the third top portion 17 </ b> C of the second connecting member 17 are displaced in a direction approaching each other in the axial direction of the cylinder device 22. As a result, the piston rod 22B of the cylinder device 22 generates a damping force while returning from the extended position to the neutral reduced position.
図7に示すように、上梁1Aが下梁1Bに対して、二点鎖線で示す中立位置から実線で示す右側位置に変位した場合は、上梁1Aと共に左柱2Aの上端および右柱2Bの上端が中立位置に対して右方向に変位することにより、第1棒状体12も右方向に向けて変位する。このとき、第1棒状体12は、上梁1Aに対して揺動不能に固定されているため、第1棒状体12は、例えば、上梁1Aとのなす角度が中立位置のときのなす角度のまま、右方向に変位する。これに伴って、第1連結部材16が右方向に変位するが、このとき、第1連結部材16は、第1,第2ガイド部材18,19によって第2連結部材17との距離が一定に維持されるため、第1連結部材16は、右方向に変位しつつ時計回り方向に揺動する。また、第1,第2ガイド部材18,19と接続されている第2連結部材17は、第1連結部材16が右方向に変位することに伴って、第1の頂部17Aのピン17A1を中心として時計回り方向に揺動する。
As shown in FIG. 7, when the upper beam 1A is displaced from the neutral position indicated by the two-dot chain line to the right position indicated by the solid line with respect to the lower beam 1B, the upper beam 1A and the upper end of the left column 2A and the right column 2B When the upper end of is displaced to the right with respect to the neutral position, the first rod-like body 12 is also displaced toward the right. At this time, since the first rod-like body 12 is fixed so as not to swing with respect to the upper beam 1A, the first rod-like body 12 is, for example, an angle formed when the angle formed with the upper beam 1A is the neutral position. Displace to the right. Accordingly, the first connecting member 16 is displaced in the right direction. At this time, the distance between the first connecting member 16 and the second connecting member 17 is made constant by the first and second guide members 18 and 19. Therefore, the first connecting member 16 swings in the clockwise direction while being displaced in the right direction. The second connecting member 17 connected to the first and second guide members 18 and 19 is centered on the pin 17A1 of the first top portion 17A as the first connecting member 16 is displaced in the right direction. Swings in the clockwise direction.
これにより、ピストンロッド22Bが接続されている第1連結部材16の第3の頂部16Cとシリンダ22Aが接続されている第2連結部材17の第3の頂部17Cとは、シリンダ装置22の軸方向の互いに離れる方向に変位する。このため、シリンダ装置22のピストンロッド22Bが中立状態の縮小位置から伸長方向に変位する。そして、シリンダ装置22は、シリンダ22A内をピストンが変位することにより減衰力を発生して、構造物の振動エネルギを吸収する。
Thus, the third top portion 16C of the first connecting member 16 to which the piston rod 22B is connected and the third top portion 17C of the second connecting member 17 to which the cylinder 22A is connected are in the axial direction of the cylinder device 22. Displacement in the direction away from each other. For this reason, the piston rod 22B of the cylinder device 22 is displaced in the extending direction from the reduced position in the neutral state. The cylinder device 22 absorbs vibration energy of the structure by generating a damping force when the piston is displaced in the cylinder 22A.
一方、上梁1Aが下梁1Bに対して、実線で示す右側位置から二点鎖線で示す中立位置に戻るときは、第1連結部材16が左方向に変位しつつ反時計回り方向に揺動すると共に、第2連結部材17が反時計回り方向に揺動する。このとき、第1連結部材16の第3の頂部16Cと第2連結部材17の第3の頂部17Cとは、シリンダ装置22の軸方向の互いに近付く方向に変位する。これにより、シリンダ装置22のピストンロッド22Bが、伸長位置から中立状態の縮小位置に戻りつつ、減衰力を発生する。
On the other hand, when the upper beam 1A returns from the right position indicated by the solid line to the neutral position indicated by the two-dot chain line with respect to the lower beam 1B, the first connecting member 16 swings counterclockwise while being displaced leftward. At the same time, the second connecting member 17 swings counterclockwise. At this time, the third top portion 16 </ b> C of the first connecting member 16 and the third top portion 17 </ b> C of the second connecting member 17 are displaced in a direction approaching each other in the axial direction of the cylinder device 22. As a result, the piston rod 22B of the cylinder device 22 generates a damping force while returning from the extended position to the neutral reduced position.
かくして、第1の実施の形態によれば、制振装置11は、構造物の筋交いとして構成されている。この場合、制振装置11は、上梁1Aと右柱2Bとに上部固定部材13を介して固定された第1棒状体12と、下梁1Bと左柱2Aとに下部固定部材15を介して固定された第2棒状体14と、第1棒状体12の他端に第1連結部材16を介して第1連結部材16のピン16C1に一側が連結され、第2棒状体14の他端に第2連結部材17を介して第2連結部材17のピン17C1に他側が連結されたシリンダ装置22と、を含み、第1連結部材16および第2連結部材17は、揺動可能なリンク機構である構成としている。これにより、シリンダ装置22に曲げの力が加わることを低減(抑制)して、シリンダ装置22に対する力の伝達効率を高くすることができる。
Thus, according to the first embodiment, the vibration damping device 11 is configured as a brace of a structure. In this case, the vibration damping device 11 includes a first rod 12 fixed to the upper beam 1A and the right column 2B via the upper fixing member 13, and a lower fixing member 15 to the lower beam 1B and the left column 2A. The other end of the second rod-shaped body 14 is connected to the pin 16C1 of the first coupling member 16 via the first coupling member 16 to the other end of the second rod-shaped body 14 fixed to the second rod-shaped body 12. And a cylinder device 22 having the other side connected to the pin 17C1 of the second connecting member 17 via the second connecting member 17, and the first connecting member 16 and the second connecting member 17 are swingable link mechanisms. It is set as the structure which is. Thereby, it is possible to reduce (suppress) the application of a bending force to the cylinder device 22 and increase the transmission efficiency of the force to the cylinder device 22.
ここで、図11は、比較例による制振装置101を示している。制振装置101は、第1棒状体102、上部支持部材103、第2棒状体104、下部支持部材105、シリンダ装置106を有している。制振装置101は、第1の実施の形態の制振装置11と異なり、リンク機構としての連結部材を介さずに、シリンダ装置106が第1棒状体102および第2棒状体104に直接接続されている。
Here, FIG. 11 shows a vibration damping device 101 according to a comparative example. The vibration damping device 101 includes a first rod-like body 102, an upper support member 103, a second rod-like body 104, a lower support member 105, and a cylinder device 106. Unlike the vibration damping device 11 of the first embodiment, the vibration damping device 101 has a cylinder device 106 directly connected to the first rod-like body 102 and the second rod-like body 104 without using a connecting member as a link mechanism. ing.
このような比較例による制振装置101は、構造物の振動時に、第1棒状体102および第2棒状体104を介して直接シリンダ装置106に構造物の振動が入力される。このとき、図11中に二点鎖線で示すように、シリンダ装置106には、シリンダ装置106の中心軸線方向(伸縮方向)の力P1と、左,右方向の力P2とが加わる。即ち、左,右方向の力P2に基づいて、シリンダ装置106に曲げの力が加わる可能性がある。また、シリンダ装置106に加わる力が中心軸線方向の力P1と左,右方向の力P2とに分散してしまうので、シリンダ装置106に対する力の伝達効率が悪くなる可能性が考えられる。
In the vibration damping device 101 according to the comparative example as described above, the vibration of the structure is directly input to the cylinder device 106 via the first rod-like body 102 and the second rod-like body 104 when the structure vibrates. At this time, as indicated by a two-dot chain line in FIG. 11, a force P1 in the direction of the central axis of the cylinder device 106 (stretching direction) and a force P2 in the left and right directions are applied to the cylinder device 106. That is, there is a possibility that a bending force is applied to the cylinder device 106 based on the left and right direction force P2. Further, since the force applied to the cylinder device 106 is dispersed into the force P1 in the central axis direction and the force P2 in the left and right directions, there is a possibility that the transmission efficiency of the force to the cylinder device 106 is deteriorated.
